A retrospective study was carried out on 120 patients with brain abscess treated at Cho Ray Hospital from Oct 2000 to Feb 2003. 91% patients were hospitalized on emergency. The patients were diagnosed easily and quickly brain abscess by CT. 80 patients (70.8%) underwent emergency surgeries and the commonest applied technique (73.3%) was punction and pus drainage. Antibiotic were indicated suitably for patients, corticoids were prescribed for 31.6% patients with severe brain edema, antiepileptic drugs were given for patients with convulsions. Twelve patients (10%) died because of too late hospitalizations with general complications and/or brain hernia. Patients with brain abscess were commonly arrived late; the majority of them were admitted on emergency. Although having CT for accurate diagnosis and surgery and new antibiotic generations, the mortality rate is still high

Introduction: In Vietnam, the andrology field has been developed in recent years. Some studies have indicated the reasons for male infertility. Amongst them, the most common reason is abnormal semen. Asthenozoospermia rate was found at a higher ratio in abnormal semen analysis. \r\n', u'Objectives: To identify the characteristics of sperm and concentration of FSH, LH and Testosterone in serum; and the association between the sperm morphology and sperm motility as well as the concentration of FSH, LH and Testosterone in serum of asthenozoospermia men. \r\n', u'Subjects and methods: 90 asthenozoospermia male partners of infertile couples. The semen was analyzed at the Laboratory for Tissue and Embryo Preservation, Hanoi Medical University. The hormone concentration was measured by the Automated Chemiluminescence System ACS 180. \r\n', u'Results: The mean semen volume: 3.0 \xb1 1.1 (ml); sperm density: 104.7 \xb1 86.7 million/ml; rapid motility rate: 5.9 \xb1 6.4 (%); sperm vitality rate: 67.4 \xb1 20.1 (%); normal morphology rate: 14.4 \xb1 6.9 (%). In serum, the concentration of FSH was 5.3 \xb1 2.5 lUlL; LH: 4.1 \xb1 1.8 IU/L. Testosterone: 18.3 \xb1 9.4 nmol/L. Conclusions: Among the studied asthenozoospermia men, normal semen volume was found at 91.11 %; normal sperm vitality parameter: 84.4%; normal morphology parameter: 45.56%; normal level of FSH concentration: 47.7%; normal level of LH concentration: 26.66%; normal level of Testosterone concentration: 78.89%. There was a strong association between the sperm morphology and sperm motility as well as serum Testosterone concentration. \r\n', u'

Background: Can Gio mangrove forest is bio-diversified area. There is few studies on medical arthropod in Can Gio mangrove forest until now. Objective: To study bio-diversified feature and identify species with disease transmitting role. Subject and Method: In 2007, medical arthropod surveys were conducted at 3 sites located in the natural conserve zone- Can Gio mangrove forest. A cross-sectional study was used. Results and Conclusions: A total of samples of 6178 individuals of medical arthropod belonging to 65 species have been collected, including 3 species of flea (Siphonaptera), 1 species of ticks (Ixodidae), 6 species of chiggers (Trombiculidae), 6 species of mites (Gamasoidea), 25 species of flies (Muscoidea) and 24 species of mosquitoes (Culicidae). They belong to 37 genus, 17 families, 3 orders (Siphonaptera, Acarina and Diptera), and 2 classes (Insecta and Arachnida). 20 species having epidemiological role were found in Can Gio mangrove forest. The rate of Anopheles epiroticus biting human at night indoor, outdoor and daytime indoor is rather high, especially at the end of dry season at centre of the forest.

Objectives: The prevalence of posttraumatic stress disorder (PTSD) has increased, particularly among individuals who have recovered from coronavirus disease 2019 (COVID-19) infection. Health literacy is considered a “social vaccine” that helps people respond effectively to the pandemic. We aimed to investigate the association between long COVID-19 and PTSD, and to examine the modifying role of health literacy in this association. Methods: A cross-sectional study was conducted at 18 hospitals and health centers in Vietnamfrom December 2021 to October 2022. We recruited 4,463 individuals who had recovered from COVID-19 infection for at least 4 weeks. Participants provided information about their sociodemographics, clinical parameters, health-related behaviors, health literacy (usingthe 12-item short-form health literacy scale), long COVID-19 symptoms and PTSD (Impact Event Scale-Revised score of 33 or higher). Logistic regression models were used to examine associations and interactions. Results: Out of the study sample, 55.9% had long COVID-19 symptoms, and 49.6% had PTSD.Individuals with long COVID-19 symptoms had a higher likelihood of PTSD (odds ratio [OR], 1.86; 95% confidence interval [CI], 1.63–2.12; p < 0.001). Higher health literacy was associated with a lower likelihood of PTSD (OR, 0.98; 95% CI, 0.97–0.99; p = 0.001). Compared to those without long COVID-19 symptoms and the lowest health literacy score, those with long COVID-19 symptoms and a 1-point health literacy increment had a 3% lower likelihood of PTSD (OR, 0.97; 95% CI, 0.96–0.99; p = 0.001). Conclusion Health literacy was found to be a protective factor against PTSD and modified the negative impact of long COVID-19 symptoms on PTSD.

Backgroud: The aim of this study is to update on antibiotic resistance of common pathogenical bacteria isolated in Hue University of Medicine and Pharmacy Hospital (Hue UMP Hospital). Methodology: Use of the agar disk diffusion method to test the susceptibility to antimicrobial agents of 3709 bacterial strains from infected patients hospitalized in Hue UMP Hospital in 2020 - 2022. Results: Among 3709 strains of pathogenical bacteria isolated, S.aureus was found with the rate of 29.9%, followed by E. coli (24.5%), Pseudomonas aeruginasa (17.8%), Enterococcus spp. (11.8%), Klebsiella spp (9.7%) and Acinetobacter spp (4.1%). The proportion of bacterial isolates has changed, but Staphylococcus aureus is still highest rate. S.aureus is resistant to many antibiotics, but MRSA strains have decreased significantly, from 73.3% in 2020 to 62.5% in 2022. Pseudomonas aeruginosa was resistant to some of the group A recommended antibiotics such as ceftazidime, piperacillin-tazobactam with the rate of 56.6% and 48.7%. The percentage of E. coli with ESBL strains (+) was at 28.2% - 30.3%. Enterococus spp strains are still sensitive to vancomycin (83.1% - 91.9%). The rate of Klebsiella ESBL (+) is only 6.9% to 8.2%. The strains of Acinetobacter spp were highly resistant to Piperacillin (100%) and Ceftriaxone (96.5%) but they are still sensitive to imipenems 70 - 71%, highly sensitive to Doxycillin (95.2%) and Cefotaxime (88.4%). Conclusion: Many bacterial strains are resistant to many commonly antibiotics. Providing timely, regular, and effective management of antibiotic resistance patterns for common pathogenic bacteria in hospitals, will help reduce the risk of bacterial resistance.
